I am rooted with s-off running on a ATT simcard but still can't boot in CWM recovery. In rom manager it says: current recovery Clockworkmode 3.0.2.4
Whenever I attempt to boot into recovery the MT4G comes up it reboots and it comes up agains and boots regularly. Any thoughts?
I followed all the instructions in this thread and am at the 85.xxx bootloader
http://forum.xda-developers.com/showthread.php?t=858996
I am bone stock other since I've not be able to get into recovery mode. Would a factory reset help?
Do it manually. Go to the bootloader and load recovery from there, or use adb and type adb reboot recovery.
adb does the same thing it attempts to get into recovery then goes blank and reboots regular and same thing with hboot.
Do you have fastboot on?
Nope. Fastboot is off. I can't even factory reset the phone. It just reboots like with everything else

most likely it feels as if the recovery image didn't take.
Code:
adb reboot bootloader
from there select "recovery" and see what boot loader you are using. If you have the engineering screen manually flash it.

1. Download CWR3. - link supplied above
2. Save to your Android SDK tools (c:\android-sdk-windows\tools) or platform-tools (c:\android-sdk-windows\platform-tools) folder and rename to recovery.img
3. Turn off your phone.
4. Hold the volume down button + power until you boot to a white screen.
5. Use the volume rocker to select FASTBOOT then press the power button to select it.
6. Connect your phone.
7. Open up a windows command prompt and navigate to your sdk tools or platform tools folder. tools (c:\android-sdk-windows\tools) or platform-tools (c:\android-sdk-windows\platform-tools)
8. Type
Code:
FASTBOOT DEVICES
to make sure your computer "sees" your phone and is ready to flash the recovery. You should get a serial number and then the word fastboot as the output.
9. Type
Code:
fastboot flash recovery recovery.img
and press enter. Give it a minute to do it's thing. You should get a message that says writing recovery and success.
10. Unplug your phone and use the volume rocker to select BOOTLOADER and then again to select RECOVERY and you should be booted into the orange menu of Clockwork Recovery 3

It says fastboot isn't a recognized command when I type FASTBOOT DEVICES
also for the bootloader part. It loads real quick and it says something about no image or wrong image in the lines of code that loads on the screen then disappears
Are you using Linux? If so, cd to platform-tools and use ./fastboot instead of fastboot. Otherwise try updating adb and see if it works. Also, the random text is the phone searching for PD15IMG or another restore image. Disregard that, unless you want to flash the stock unrooted image.
Here We have the Root And CWM for Nexus 7 On Android 4.2.2!
Step 1 - Download Android SDK from the Android Developers website and install with USB drivers. See: How to Set Up Android SDK (Fastboot / ADB) on Windows.
Step 2 - Enable USB Debugging mode in your Nexus 7 tablet.
Step 3 - Download Fastboot and extract it in android-sdk-windowsplatform-tools directory. Create directory if not already there.
NOTE: Skip Steps 1, 2, 3 if you already have them.
Step 4 - Download SuperSU v1.04 (UPDATE-SuperSU-v1.04.zip) and copy it to your sdcard on your Nexus 7 tablet.
Step 5 - Make sure you have backup your data as it will be removed. Then switch OFF your Nexus 7.
Step 6 - Download recovery-clockwork-touch-6.0.2.3-grouper.img and copy/paste it in the android-sdk-windowsplatform-tools directory.
Step 7 - Now go into Fastboot Mode on Nexus 7. How? Press Volume Down + UP + Power key for a few seconds till you see some text on the screen.
Step 8 - Navigate to android-sdk-windowsplatform-tools directory and open Command Prompt (Shift + Right-click > Open Command Prompt).
Step 9 - Type in the following command and press Enter.
fastboot flash recovery recovery-clockwork-touch-6.0.2.3-grouper.img
Click to expand...
Click to collapse
Step 10 - Once completed, choose RECOVERY MODE from the Fastboot menu and enter Recovery Mode.
Step 11 - Then scroll down to “flash zip from SD card” and press the Power button to select it.
Step 12 - Press the Power button again and select “choose zip from sdcard”.
Step 13 - Now using your volume keys, navigate to the UPDATE-SuperSU-v1.04.zip file that you copied to your SD card and select it using the Power button. Confirm the installation on the next screen and the installation procedure should start now.
Step 14 - After the installation completes, go to “+++++Go Back” and reboot the phone by selecting “reboot system now” from the recovery menu. Then Choose yes flash recovery back (this will make CWM your permanent recovery mode)
That’s it. Your Nexus 7 is now rooted on Android 4.2.2 JDQ39 software version of Jelly Bean and even has a custom CWM recovery installed. Check for the SuperSU app in your apps list to verify.

Step 4 and step 7
I am a little confused about step 4 as I didn't think any nexus 7's had a SD card slot. I purchased mine right from google. I just put the zip file directly on the device itself and I know from my experience with my old Nexus One that this works too, just wondering who is selling the one with SD card slots. My second question, and really the more important one is step 7. I have tried to make the device go into fastboot several times and when I hold the volume keys down, the device boots to a black screen with no ability to do anything after that. If I mess with the power button (meaning I hold it in for a long time then let it out, and do this several times) I can get the device to preform a normal boot. Any thoughts?
thanks
Thanks its worked for my nexus 7..

Thanks a million man! I was having all kinds of trouble updating to 4.2.2 and finally figured that out. Then I was having problems rooting again until I found this. Your method worked great but I used TWRP instead and it still did the trick. Thanks again.
I tried this but when I want to flash the recovery, my fastboot.exe will then not respond and will try to close. What gives?

Just a quick note here, to enter Fastboot Mode you just need to turn the Nexus 7 off, then turn on again, soon as you see the Google logo press the Volume Down key and hold (Hold both Power button and Volume Down Key).
No need for holding the power button, the vol down button does the whole trick
worked for me. thanks very much

re-install the fastboot with all it's extensions in the same folder!
If you want to use fastboot by a easy way, use this guide you don't need adb line command, just fastboot line command and it's an child game by this way
If you have got a problem with your adb or fastboot or recovery....it's very simply and faster
use this:
Download this file "Fastboot.zip"
Install this file somewhere in one folder which is named "fastboot" on your PC
=> disk C: root
Unzipped this file on the folder "fastboot" and you will find 3 files:
- adb.exe
- AdbWinApi.dll
- fastboot.exe
and when you need to push something by the bootloader, you can use it.
Don't forget to push on this folder the file that you need. For exemple: boot.img or a recovery.img, etc...
The line command is :
Code:
c:\fastboot>
Enter
Code:
c:\fastboot>fastboot flash recovery recovery.img
Enter
If you want to flash the "recovery.img" file
If you want to flash a boot.img:
Code:
c:\fastboot>fastboot flash boot boot.img

Yes, it is a prerequisite if you want to root your android device.
Ok, so I am running the 4.2.2 update, and after jumping through numerous hoops trying to have my device recognized by adb, I just want to make sure that my very first step should be to boot up in fastboot mode and then issue the following command...
"fastboot oem unlock"
???
Then I can go ahead and proceed to flashing the CWM recovery and flashing the SuperSU file...?

EDIT: I've tried multiple times, but everytime I boot into "fastboot" mode, which I guess is another way for saying the bootloader, ADB loses its connection with my Nexus 7! Also, if it helps anyone to know, I'm running Win7 64-bit.....I'm not sure if that matters, but the first time I booted up into fastboot mode, my computer recognized it and installed it as an "Android Bootloader Interface" in the Device Manager! When the device boots up normally, ADB does recognize it again, and it also shows up differently in the Device Manager (Android Composite ADB Interface)! ANY help or suggestions would be greatly appreciated, as I obviously can't issue commands to a device that ADB can't see when it's in fastboot mode!

Hi, vmancini3...
Forget about ADB when your tablet is in FASTBOOT/BOOTLOADER mode...
Here are the salient commands....
Code:
fastboot devices
- should return a serial number to confirm your FASTBOOT connection -
Code:
fastboot oem unlock
- will unlock the BOOTLOADER and will WIPE and FACTORY RESET THE DEVICE; unfortunate, but necessary .
--------------------
With the BOOTLOADER unlocked, begin to set up your Nexus 7 again... as though it was a brand new, just purchased tablet... ie., country, regionalization, WiFi key... etc.
Go online with your Nexus 7 browser (Chrome), and download Chainfire's SU Updater .ZIP package from here...
http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip
Upon completion of this download, shut down the tablet.
--------------------
Reboot again into FASTBOOT/BOOTLOADER mode... VOL down button + POWER ON button.
From your PC, run this command...
Code:
fastboot flash recovery recovery.img
....where the recovery.img is your CWM or TWRP .img file.
Both of which are available here...
CWM - http://www.clockworkmod.com/rommanager
TWRP - http://www.teamw.in/project/twrp2/103
--------------------
Congratulations.... you've just FLASHED a CUSTOM RECOVERY!!!
--------------------
When the self-congratulatory round of self applause has died down, ... and with the Nexus 7 still in FASTBOOT/ BOOTLOADER MODE, use the VOL buttons to navigate and the POWER button to select... reboot into RECOVERY.
Using the new CUSTOM RECOVERY, flash Chainfires SU updater package that you downloaded earlier... usually found in the /download folder...
Done.
Reboot.
Rooted.
--------------------
I really don't understand why some people seem to have a problem with this procedure... it takes less time doing it, than actually describing how to do it.
Rgrds,
Ged.

i have literally the same problem and i can't get out of this!
sony didn't make the update for xperia c4 to start automatically, so i flashed marshmallow 6.0 in this device.
And now, i can't get in recovery mode, i used a tons of guides, i try to do it with codes on sdk, on sony's flashtool(emma), on adb, it's totally useless i think there isn't a way to get the recovery mode on xperia c4 with marshmallow 6.0.
Sony, wtf?
no one?
Any helps?.. it is really impossible to root this phone?
same problem here too.. need help

Search for stock recovery or TWRP recovery .img file on web. ( Remember, Google is your friend! ) Rename it to recovery.img and put it into the adb folder. Then, open a command prompt there ( as admin ) then type: cd <directory to adb folder> e.g. cd C:\adb then boot into fastboot mode or bootloader and then type: fastboot flash recovery recovery.img . Now it should flash a new recovery to your recovery partition.
P.s. You need to unlock your bootloader! But you need to backup your files cuz this is going to delete them!!! Go to setings> slide down> click on about your phone> click 7 times on build till you see a message like: "You are a developer!"> then click back button> go to "Developer settings"> and find an option called: "Oem Unlock." toggle it> Then go to fastboot mode or bootloader mode and in fastboot type: "fastboot oem unlock" or "fastboot oem go-unlock" then click "Yes" when prompting. BUT you can also boot in edl mode and flash it without unlocking bootloader. To do this, try power combinations, or go on google and search for them. It may also happen that you don't have an EDL mode, so you'll have to unlock the bootloader. So: What you have to do.
1. If you have a locked bootloader, unlock it.
2. Get a recovery image ( img. ).
3. Flash it!
Well that's it! Hope you understand me! Happy flashing!

I tried with different drivers etc. but its just don't work, i downloaded TOOL ALL IN ONE, but this said that device was found but not said what or which device, only when phone is normally started i see it on the list of "adb devices" and in TOOL ALL IN ONE. Please help thanks in advance =)
Fastboot is an entirely different mode from adb, and as such it requires a different tool. In the console there is a command "fastboot", which is what you need to use to interact with the phone in fastboot mode. You can boot into fastboot mode from power off with the USB to computer plugged in by holding Volume Down, or it might be possible with TOOL ALL IN ONE, I haven't used it much.
Some basic commands:
fastboot flash unlock path/to/unlock.bin # This will flash the unlock bin
fastboot getvar unlocked # This will check if the device is unlocked
fastboot reboot # This will reboot the phone into normal mode, since powering off by holding the power button is a pain
To flash TWRP, there's a more advanced process with some specific requirements, but I'd be happy to share those if wanted.

First of all, which version of G6 do you have? The US997 one, or the H870?

Click to expand...
Click to collapse
H870
For H870 I'm not entirely sure, but I know that for the US997 you have to do a special procedure to make it permanent. Make sure you back up everything first, too.
With the phone in fastboot mode and a computer connected with fastboot installed and the twrp zip downloaded as "twrp.zip" (or whatever you want):
Make sure the bootloader is unlocked: fastboot getvar unlocked (should return "yes" or "true").
Flash the recovery: fastboot flash recovery twrp.zip (replace twrp.zip with the relative or absolute filepath/name).
Unplug the phone from the computer and reboot into recovery by holding Power and Volume Down. When the logo appears, lift your finger off the power button briefly and then continue pressing.
When you get to the factory reset menu hit yes twice, then the phone should boot into twrp (it may flash the LG logo, I've had different behavior on different phones. You won't need to hold the Power-Volume Down combo any more).
In twrp, swipe to allow modification, then in the Wipe menu select Format Data (and enter yes). This will wipe the phone, so make sure everything was backed up beforehand.
From the main menu go to the Reboot menu and select Recovery.
Here it might vary from the US997. Below are suggestions which I think are needed to have it work.
Download the no-verity-opt-encrypt zip, and connect the phone to the computer.
Once it's rebooted into recovery mode: adb push path/to/no-verity.zip /sdcard/
Then from the install menu in twrp install the zip.
Reboot into System from the reboot menu on the homescreen of twrp.
That should do it all.
Hi I was looking for a solution to fix my p10 lite that when restarting in twrp or eRecobery it threw black screen and restarted and remained in bootlogo
My device is the Was-Lx3, which was more difficult to give alone since I could not find a system and I could find one for my model and thanks to the fastboot commands it was restored from the factory
Link of the rom that I downloaded and it worked
https://mega.nz/file/DFhziCjI#c1vkVdcvKj3mR_wBb3Kbe_BAA5HUYaCtJVFLkUt9rLk
The steps is:
1 download the rom and unzip the rom
2 leave the device in fastboot mode and run Adb FASTBOOT
3 Flash the .img files I will leave the commands below
fastboot flash boot (drag the file and enter)
fastboot flash cust (same drag and enter)
fastboot flash recovery
fastboot flash system
fastboot flash userdata
ending with the flashing without disconnecting the phone Press buttons button power plus Vol + for 10s and you can enter eRecobery and download the last system you have and ready it will start normal
Even if you have the device without battery, it still works without battery, just do not disconnect the phone and doing all these steps and once the device has been restored, it will start to charge normally. I would like you to give the thank you button if it works if you do not comment below
